ncurses 6.3 - patch 20220917

+ reduce memory-leak in tic by separating allocations for struct entry
  from TERMTYPE2 (cf: 20220430).
+ improve interaction between tic -v option and NCURSES_TRACE, by
  processing the latter only when -v option does not set _nc_tracing.
+ modify curses_trace() to show the trace-mask as symbols, e.g.,
  TRACE_ORDINARY, DEBUG_LEVEL(3).
